What is your go-to online place to buy physical medium of music? And why?


The brunt of the question is pretty much covered in the title, but just curious where most people are buying any physical medium of music (vinyl, cassette, 8-track, etc.) online.

Personally, I've probably only bought a couple of items online. I mostly patronize my local independent record stores but, obviously, the selection of music available online is essentially infinite, so I'd like to start utilizing it more.

Thanks!

Oops, forgot to mention why I buy where I do - cheapest price and availability.
Records by Mail is good. I once bought a wharped record from them, and Craig said to throw it away and gave me a refund. Usually priced higher than ebay but often worth it.
I am a regular on smile.amazon.com (where they donate .5% of my purchase amounts to my favorite charity), have the Amazon credit card (giving me 5% cash back) and have an Amazon Prime membership, enjoying 2 day shipping and Amazon Streaming to my TV.

Besides all that, I find the reviews on Amazon really helpful, especially as I'm learning more about classical music.

Where's the recommendations for cassette or 8-track? Got to say I was a little amused that they were included in the list. Guess they can still be found on ebay or craigslist.
